将 Firebird Net 提供程序集成到应用程序中答案

【问题标题】：Integration of the Firebird Net provider into the application将 Firebird Net 提供程序集成到应用程序中

【问题描述】：

在我的项目中，我使用 Entity Framework 6 连接到带有嵌入式服务器的 Firebird。在安装了 Firebird Net Provider 的计算机上，我的应用运行良好，但在没有它的计算机上，应用崩溃并出现错误：

具有不变名称“FirebirdSql.Data.FirebirdClient”的 ADO.NET 提供程序未在机器或应用程序配置文件中注册

如何在配置文件中注册 ADO.NET 提供程序以避免此错误？这是我的 app.config：

  <?xml version="1.0" encoding="utf-8"?>
    <configuration>
      <configSections>
        <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

        </sectionGroup>
      </configSections>
      <startup>

      </startup>
      <entityFramework>
        <defaultConnectionFactory type="FirebirdSql.Data.EntityFramework6.FbConnectionFactory, EntityFramework.Firebird" />
        <providers>
          <provider invariantName="FirebirdSql.Data.FirebirdClient" type="FirebirdSql.Data.EntityFramework6.FbProviderServices, EntityFramework.Firebird" />
        </providers>
      </entityFramework>
      <connectionStrings>

      </connectionStrings>
      <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

        </assemblyBinding>
      </runtime>
    </configuration>

【解决方案1】：

将此添加到您的[app|web|machine].config：

<system.data>
    <DbProviderFactories>
        <add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient"/>
    </DbProviderFactories>
</system.data>

现在即使在安装了提供程序的计算机上也会出现此错误。虽然 FirebirdSql.Data.FirebirdClient.dll 位于应用程序所在的文件夹中
